Answer:

Write = if the two ratios form a proportion, and ≠ if not.

1. 2/3_≠_4/3

2.3/5 _=_9/15

3.7/6 _≠_5/6

4. 8/9_=_2/3

5. 3/4_≠_15/20

#Brainly Everyday!!

1. 2/3 ≠ 4/3

2.3/5 = 9/15

3.7/6 ≠ 5/6

4. 8/9 ≠ 2/3

5. 3/4 = 15/20

Multiply the denominator of the first fraction and the numerator of the second fraction. Place this product to the left of the equation. Compare the two products. If they are the same, then the ratios are in proportion.
